JOHN H. MOORE, OF \VELLSVILLE, OIIIO.

OlL-WELL-DRILLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 600,437, dated March 8, 1898.

Application filed June 24, 1897. Serial No. 642,108. (No model.)

To all whom it may concern:

Be it known that 1, JOHN H. MOORE, a citizen of the United States, residing at \Vellsville, in the county of Columbiana and State of Ohio, haveinvented certain new and useful Improvements in O ilWVell-Drilling Machines; and I do declare the following to be a full,clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in portable oil-well-drilling machines; and the object is to provide a simple and compact machine of this class.

To this end the invention consists in the construction, combination, and arrangement of the several parts of the same, as will be hereinafter more fully described, and particularly pointed out in the claim.

In the accompanying drawings the same reference characters indicate the same parts of the invention.

Figure 1 is a perspective view of my improved portable oil-well-drilling machine. Fig. 2 is a front view. Fig. 3 is a top plan view. Fig. 4 is a transverse section on the line of the walking-beam fulcrum. Fig. 5is a perspective detail of one of the fulcrumbearings for the walking-beam. Fig. 6 is a transverse section on the line 6 6 of Fig. 3. Fig. 7 is a detail plan of the sand-pump-driving mechanism.

1 represents a suitable framework which constitutes the base of the machine. This may be provided with the usual carryingwheels for conveniently transporting the machine from point to point.

2 2 represent vertical parallel samson-posts rigidly fixed in the frame and braced longitudinally by the'diagonal braces 3 3, so as to give strength and rigidity to the same.

4 represents a saddle fixed on the upper ends of the Samson-posts 2 2, upon which rests the bearing-shoe 5, connected about midway to the parallel walking-beams 6 6, which are fulcrumed thereon. These parallel Walking-beams are provided with suitable transverse braces 7 7, and their forward ends extend through vertical guide-brackets 8 8, fixed to the opposite sides of the lower fixed section 9 of the derrick 10, which is suitably fixed at its lower end to the frame 1. The brace 7 is provided with the depending hook 7 from which the temper-screw is suspended. The upper section 11 of the derrick is secured to the lower section by suitable straphinges 12 12.

64 and 65 represent vertical fixed braces removably secured by the bolts 66 66 to the front faces of the contiguous sections 9 and 11 of the derrick, so as to extend above and below the hinges 12. The diagonal brace 13 extends from the upper end of the derrick 10 rearwardly to a horizontal frame 14, which is suitably fixed to the frame 1 by studposts 15 15.

16 represents a driving-shaft mounted in bearings on the rear end of the frame 14, and it is provided with a band-wheel 17,which receives motion from an engine. (Not shown.)

18 18 represent parallel crank-arms fixed on the outer end of the shaft 16, and to their outer ends are pivoted the lower ends of the connecting-rods 19 19, which in turn are pivoted to the rear ends of the walking-beams 6 6, so as to impart an oscillating motion to the same.

20 represents a coupling-collar mounted on the shaft 16, and it is provided with a keyway engaging a longitudinal key on said shaft to allow it to slide longitudinally while it is being rotated. A circumferential groove 23 in said collar engages the forked end of a handlever 24, fulcrumed 011 the bolt 25, fixed in the frame 1 1.

26 represents a sprocket-Wheel loosely j ournaled on the shaft 16, and its hub 27 is formed with a clutch-collar 28, which is adapted to engage a corresponding clutch-collar 28' on the shaft. A sprocket-chain 29 extends from the sprocket wheel 26 to a corresponding sprocket-Wheel 30 on the counter-shaft 31, which is mounted in suitable bearings fixed on the frame 14.

32 represents a drum fixed to the countershaft 31, and from it a rope or cable 33 extends over a grooved guide-pulley 34, journaled in an orifice 35 in the stanchion 36, thence under a corresponding pulley 37 journaled in a bracket 38, fixed on the cross-brace 39, secured to the walking-beams, and from this pulley the rope or cable extends vertically upward to a grooved crown-pulley 40, journaled in the upper end of the derrick 10,

and from this guide-pulley the said rope or cable extends downwardly, and its lower end is provided with the usual clamp 41, which receives the ordinary tools employed in welldrilling, one of which, 41, is shown in Fig. 1. By reference to said Fig. 1 it will be seen that when an oscillating movement is imparted to the walking-beams through the medium of the driving-shaft 16 a vertical reciprocating movement will be imparted to the boring-tool 41 in a simple and effective manner. Whenever it is desired to raise the boring-tool for the purpose of lowering the sand-pump, the lever 24 is operated to connect the clutches on the shaft 16, which raises the boring-tool and allows the sand-pump to be inserted.

42 represents the driving-shaft of the sandpump, and it is provided with a sprocketwheel 43, which projects into the path of the sprocket-chain 50, engaging a sprocket-wheel 51 on the shaft 31, by means of which the sand-pump may be conveniently manipulated.

This shaft 42 is provided with a brake-wheel 52, encompassed by a brake-strap 53, operated by a brake-lever 54. The opposite end of said shaft 42 is provided with a frictionwheel 55,which is arranged to engage a smaller friction-wheel 56 on the sand-pump shaft 57, and from said shaft the sand-pump rope 58 extends over a pulley 59 in the derrick 10, and thence downwardly, where its lower free end is connected to the sand-pump 60. This end of the shaft 57 is journaled in a horizontal slot 61 in a fixed bearing-block 62, and the lower bifurcated end of a bell-crank lever 63 engages said journal to move the frictionis also fixed on the shaft'31, and it is encompassed by a brake-strap 68, from which a brake-lever 69 extends to the front end of the machine for conveniently controlling the descent of the boring-tool.

Although I have specifically described the construction and relative arrangement of the several elements of my invention, I do not desire to be confined to the same, as such changes or modifications may be made as clearly fall within the scope of my invention without departing from the spirit thereof.

Having thus fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent of the United States, is-

An oil-well-drilling machine,comprising the main frame 1, the auxiliary frame 14,mounted parallel therewith; the vertical double samson-posts 2 2, fixed at their lower ends to said main and auxiliary frames, the saddle 4, connecting the upper ends of said Samson-posts, the double parallel walking-beams 6 6, the bearing-shoes 5 5, fixed to said beams and having a bearing in said saddle, the derrick 10, connected at its lower end to said main and auxiliary frames, the section 11, hinged to the derrick 10, and the removable braces 64 65, detachably secured to the abutting hinged ends of said derrick, and the detachable diagonal braces 13, connecting the hinged portion of the derrick with the auxiliary frame, the stanchion 36, provided with the pulley 34, and fixed to the frames 1 and 14, the counter-shaft 31, journaled in the frame 14, the drum 32, fixed on said counter-shaft, the cable 33, extending from said drum over the pulley 34, thence over the pulley 37,-

mounted between the beams 6 6, and over the crown-pulley 40 journaled in the upper end of the derrick, substantially as shown and described.

In testimony whereof I hereunto affix my signature in presence of two witnesses.

JOHN H. MOORE. Witnesses: J NO. W. RILEY, HENRY THoRN'.
